Avatar sequels to begin production next October
Avatar star Sam Worthington revealed on the Australian radio program Fitzy and Wippa that production will begin on Avatar 2, Avatar 3 and Avatar 4 next October.

"They are still writing it. I think Jim is building the ship to Pandora to be honest. We are going to start this time next year and we will do two, three and four. I'll be grateful if it finishes."

Back in August, we reported that Avatar director James Cameron hired Josh Friedman to write Avatar 2, with Shane Salerno (Savages) and the Rise of the Planet of the Apes writing team of Rick Jaffa and Amanda Silver writing Avatar 3 and Avatar 4.

Sam Worthington and Zoe Saldana are expected to reprise their roles from Avatar, although no other cast members have been officially announced. James Cameron is also producing with Jon Landau, through their Lightstorm Entertainment company.
